Association between overweight and central interleukin-6 in a nonclinical adult population.

Aim: Overweight is associated with low-grade systemic inflammation. However, its effect on neuroinflammation remains unclear. We examined the possible association between overweight and neuroinflammation using cerebrospinal fluid (CSF) in a nonclinical adult population in Japan.

Fentanyl-Type Antagonist of the μ-Opioid Receptor: Important Role of Axial Chirality in the Active Conformation.

In recent years, synthetic opioids have emerged as a predominant cause of drug-overdose-related fatalities, causing the "opioid crisis." To design safer therapeutic agents, we accidentally discovered μ-opioid receptor (MOR) antagonists based on fentanyl with a relatively uncomplicated chemical composition that potentiates structural modifications. Here, we showed the development of novel atropisomeric fentanyl analogues that exhibit more potent antagonistic activity against MOR than naloxone, a morphinan MOR antagonist.

The impact of concomitant Sjögren's disease on rheumatoid arthritis disease activity: a systematic review and meta-analysis.

Objectives: Rheumatoid arthritis (RA) and Sjögren's syndrome (SS) frequently co-exist but the consequence for RA disease activity of having concomitant SS (RA/SS) is not well established. We conducted a systematic review and meta-analysis to investigate the impact of SS on disease outcomes in individuals with RA.

Methods: We searched Web of Science (Core Collection, FSTA, Medline), PubMed and Cochrane databases, without language restriction.

Recurrence rate after posterior percutaneous screw fixation without anterior debridement for pyogenic spondylitis compared with conservative treatment: a propensity score-matched analysis.

Purpose: Previous studies have shown that percutaneous pedicle screw (PPS) posterior fixation without anterior debridement for pyogenic spondylitis can improve patient quality of life compared with conservative treatment. However, data on the risk of recurrence after PPS posterior fixation compared with conservative treatment is lacking. The aim of this study was to compare the recurrence rate of pyogenic spondylitis after PPS posterior fixation without anterior debridement and conservative treatment.

Risk Factors for Mortality From Aortic Aneurysm and Dissection: Results From a 26-Year Follow-Up of a Community-Based Population.

Background Aortic aneurysm rupture and acute aortic dissection are life-threatening conditions and represent an ever-growing public health challenge. Comprehensive epidemiologic investigations for their risk factors are scant. We aimed to investigate risk factors associated with mortality from aortic diseases through analysis of a community-based Japanese cohort.
